    摘要: A process for forming a bipolar junction transistor (BJT) in a semiconductor substrate and a BJT formed according to the process. A buried isolation region is formed underlying BJT structures to isolate the BJT structures from the p-type semi-conductor substrate. To reduce capacitance between a BJT subcollector and the buried isolation region, prior to implanting the subcollector spaced-apart structures are formed on a surface of the substrate. The subcollector is formed by implanting ions through the spaced-apart structures and through a region intermediate the spaced-apart structures. The formed BJT subcollector therefore comprises a body portion and end portions extending therefrom, with the end portions disposed at a shallower depth than the body portion, since the ions implanting the end portions must pass through the spaced-apart structures. The shallower depth of the end portions reduces the capacitance.

    摘要: A resistor formed on a material layer of a semiconductor integrated circuit and a method for forming the resistor. The resistor comprises a region of resistive material with a plurality of conductive contacts or plugs in electrical contact with and extending away from the resistive material. A first and a second interconnect line are formed overlying the plugs and in conductive contact with one or more of the plurality of plugs, such that a portion of the resistive material between the first and the second interconnect lines provides a desired resistance. According to a method of the present invention, the plurality of conductive contacts are formed using a first photolithographic mask and the first and the second interconnect lines are formed using a second photolithographic mask. The desired resistance is changed by modifying the first or the second mask such that one or more dimensions of a region of the resistive material between the first and the second interconnect lines is altered.

    摘要: A method of manufacturing a semiconductor device using shallow trench isolation is provided, wherein a plurality of protrusions are formed in the exposed surface of the mask layer overlying the active area of the device. The protrusions are preferably formed by forming a photo-resist layer on the surface of the mask layer and patterning the photo-resist layer such that the photo-resist layer defines a plurality of protrusion areas and a depression area within the defined active area. A portion of the mask layer is removed in the defined depression area to form a plurality of protrusions in the mask layer. Thereafter, a dielectric layer is deposited on the exposed surface of the mask layer and in the shallow trench and evenly planarized.

    摘要: A semiconductor manufacturing method comprises forming a leveling guard ring defining an interior area into which are fabricated one or more devices. In certain aspects, two or more matched devices, such as in a common centroid layout, are fabricated in the interior area. The guard ring is formed on at least one particular layer for a particular processing step. By the guard ring overwhelming the effect of local features' elevation differences, photoresist thereafter applied consequently has a more uniform height across the interior area, resulting in more uniform devices. A plurality of guard rings may be used that enclose respective arrays of matched devices arranged over the surface of a semiconductor wafer. Based on the equalizing effect by each of the guard rings, the respective devices arranged in the interior areas are more evenly matched to equivalent devices in far-spaced guard rings. Thus, local and global matching are achieved.

    摘要: An integrated circuit having an n-channel MOSFET device and a JFET device. The integrated circuit includes a semiconductor layer having an upper surface, an MOS transistor device formed in a doped well of a first conductivity type extending from the semiconductor upper surface and a JFET device. The JFET device includes a channel region in the semiconductor layer spaced from, and having a peak concentration positioned a predetermined distance below, the upper surface. An associated method of manufacturing includes introducing p-type dopant into the semiconductor surface to form a p-well in which the NMOS device is formed and a source and a drain of the JFET device. N-type dopant is introduced into the semiconductor surface to form an n-type region of the NMOS device below the p-well and a gate region of the JFET device. P-type dopant is introduced into the semiconductor layer to simultaneously form a higher concentration p-type region in the p-well of the NMOS device and a channel region extending between the source and drain of the JFET.
